The main problem when it comes to producing electricity from solar power is the costs. Solar panels are still considered expensive. Another problem is that you have to create a structure above the roof to install the solar panels, which…
Albuquerque to get 25% of its energy from solar by 2025
Albuquerque, New Mexico city council voted unanimously a resolution calling for the city to get 25% of its energy from solar by 2025. To reach the goal, they will invest $25 million to buy solar panels and to install them on…
Portable Solar Panels
In a world where we depend on technology, we also depend on power. Smartphones are requiring a lot of power and the worst thing can happen while you are away is to remain without battery. Yes, you can charge your…
Advantages of Solar Energy
The conservatives are coming with a lot of arguments against green and alternative energy. I don’t know the reason, but it might be because they fear the change. They are used only to work with that was given by their…
Green Energy Fight: Solar vs Wind vs Water
There is a long debate if green energy is efficient, but I do not want to get into such kind of discussions right now. It is true that green energy is not very well developed and still have flaws, but…
The state of Photovoltaic panels in the world
Photovoltaic technology is controversial. There are many popular beliefs that it is expensive, produce low amount of energy, etc. Photovoltaic power progress much faster than any other system. You can’t make the coal to produce more heat, you can’t increase…
Small PhotoVoltaic Modules
There are tons of PV modules out there you can purchase, but if you require a smaller model that doesn’t generate that much power yet is still quite potent, you will have a rough time finding one. If you find…
PhotoVoltaic Inverters
A solar inverter or PV inverter is a critical component in a Photovoltaic system. It performs the conversion of the variable DC output of the Photovoltaic (PV) modulesinto a utility frequency AC current that can be fed into the commercial electrical gridor used by a local, off-grid electrical network.…
PhotoVoltaic System Costs
A new study on the installed costs of solar photovoltaic (PV) power systems in the U.S. shows that the average cost of these systems declined significantly from 1998 to 2007, but remained relatively flat during the last few years. Costs…
PhotoVoltaic Shingles
After mentioning Photovoltaic glass in the past, here’s the even more practical version of that item. I can’t say for sure if it’s as effective as its glassy counterpart but it’s quite powerful nonetheless. It gets the job…
